mask image,
a radiographic image made either before or immediately after contrast material has been injected but before it reaches the anatomic site being examined. The image thus produced is stored in a computer and displayed on a video monitor. It is then subtracted electronically from a series of additional images. The technique enhances the image of the tissues being studied. See also remasking. Want to thank TFD for its existence?
